It shot up as soon as Reagan launched his failed campaign of anti-sex education, cutting social services for the poor and destroying the US economy into a recession that favored the rich against the poor. Since social-economical reasons are often the reason why people have abortions it is no surprise we saw abortion sky-rocket under Reagans political atmosphere that was hostile to lower class families. If people were becoming more against abortion in the 90s then how can you explain Clintons popularity in winning two elections? The a friendlier economic atmosphere, contraception education and relief from Reaganism helped reduce the abortion rate.
